Ecommerce growth partner · design, data and ads

Online stores built to sell, measured right, and scaled with ads that pay for themselves.

One person who builds the store, fixes the data and runs the ads.

Reply within 48 hours with the first thing I'd fix. No calls, no pitch.

02 · The gap

Your ads dashboard says one thing. Your bank account says another.

When tracking over-reports, the algorithm learns the wrong lesson and keeps spending on it.

Reported by Google Ads$15,000
Real revenue$1,500
A real store I audited. Same period, same ads.
  • 01Performance Max "optimizing", and no one can say what makes money
  • 02A store designed to impress, not to convert
  • 03An agency and a developer blaming each other, and you paying both
03 · Why it happens

Growth breaks at the handoffs.

  • StoreThe designer doesn't know what the ads need.
  • DataThe developer never reads a conversion report.
  • AdsThe ad manager can't touch the code.

Three vendors, three blind spots. The line breaks between them, and budget leaks through the gaps.

03 · The fix

One person. The whole stack.

I trace a problem from the ad click to the checkout code, and fix it where it lives.

04 · The method · 01 Build

Build Measure Scale

Always in this order. First, a store that converts and is ready to advertise on day one.

04 · The method · 02 Measure

Then the line becomes a number you can trust.

Tracking checked against real orders, so every decision is based on real revenue.

04 · The method · 03 Scale

Only then, climb.

Ads managed on your margins, grown step by step. Scaling on broken data only scales the waste.

05 · Proof
